I made my OC Aqua Splash then decided (I have OCD tendencies) she had to have a family, so I made her parents and a younger sis and younger brother. Here is the Splash family (I suck at naming so bear with me)

Aqua Splash (My main OC)

Name: Aqua Splash

Age: 18

Mane colors: Cerulean and Sea Green

Coat Color: Teal Blue

Eye Color: Sea Green

Race: Pegasus

Cutie Mark: A water symbol, (Which I sucked at drawing on with paint) good at things involving water, whether it's dealing with wet weather like Pegasus's do or something out in the ocean/lake etc.

She grew up in fancy Canterlot but felt like she never fit in because she just doesn't care about being all dolled up and fancy and stuff like that. She just wants a simple life, with some nice friends. She didn't make many friends in Canterlot, and no close real friends, because she just wanted to do simple things even things they'd consider "below them" like sports, running around in the dirt etc. plus she is a bit shy on top of that before she gets to know a pony real well. Not like Fluttershy shy but she is a bit reserved until she gets to know a pony and gets comfotable with them. She wanted to be a normal kid, a non Canterlot normal kid. So upon turning 18 she decided she wanted to find a place she could fit in better and quickly found Ponyville and saw that pony's in ponyville weren't all fancy or snobs and seemed rather friendly. Glad she found a place relatively quickly to hopefully fit in and settle down in there was just a few million things on her mind still. Would she fit in like she hoped? Would she be able to make friends? What would she do with her life? Could she find something to be successful at in Ponyville to make a living? She'd have to now that she got a place of her own she couldn't bum money off mom and dad anymore, she is an adult now and has to find her own way. And most of all, would she be finally be happy, here in Ponyville?

Her younger sister Starlight Splash

Name: Starlight Splash

Age: 14

Mane color: Teal Blue

Coat Colors: Oxley and Sea Green

Eye Color: Cerulean

Race: Unicorn

Cutie Mark: A Star, for magic (pretend it's there LOL) She is naturally good at magic but isn’t Twilight or Celestia good mind you. Unlike Twilight she isn’t super devoted to her studies of magic and practicing though she does like to sometimes in her spare time she prefers being with friends. She isn’t stuck up like many where she lives but has no problem getting along with almost anyone. When something is hard for her though she gets frustrated really easily and will blow up (not literally) and possibly give up if it takes her what she thinks is too long to get it right. She can be a bit of a perfectionist to a fault.

Her younger brother

Name: Rock Splash

Age: 11

Mane color: Gray

Coat Color: Davy's Gray

Hooves: Gray

Eye Color: Black Olive

Race: Unicorn

Cutie Mark: I can't add cutie marks cuz I suck so it would be a guitar. His parents aren't thrilled that he found a guitar and loves to "rock out", they think rocking out is low class but they weren't thrilled with Aqua moving to Ponyville with the "ruffians" but they have learned to accept their children for who they are, even if they don't agree they still love them, they mostly just want them to be happy.

Rock loves to rock out with his guitar and to music. He is great with the guitar but like many rock stars doesn’t like authority or being told what to do and will constantly break the rules. He means well but constantly gets into trouble and gives other ponies, particularly his parents, a headache. He likes to be rebellious and hates rules with a passion.

Their mother Photo Splash

Mane colors: Cerulean plus an Oxley colored headband
